A parallel plate capacitor was made with two rectangular plates, each with a length of l = 3 cm and breath of b = 1 cm. The distance between the plates is 3 µm. Out of the following, which are the ways to increase the capacitance by a factor of 10 ?

A. l = 30 cm, b = 1 cm, d = 1 µm 

B. l = 3 cm, b = 1 cm, d = 30 µm 

C. l = 6 cm, b = 5 cm, d = 3 µm 

D. l = 1 cm, b = 1 cm, d = 10 µm

E. l = 5 cm, b = 2 cm, d = 1 µm
